A "def head" is a wannabemusician and/or songwriter who thinks they are far more superior musically and technically to other musicians and songwriters when actually, for a fact, they absolutely suck.

Most def heads tend to be 13-18 years old, and have very little (one or two years) expirence playing their instrument (guitar, bass, drums, ect.). Most def heads are self-taught players and belive they do not need any form of proper lessons or music theory because they are musical geniuses right out of their mother's vagina. Some def heads are aware that they suck but dont have the balls to admit it. Def heads usually form really shitty bands with other def heads. A def head doesnt play music with any passion or feeling and only plays for money, fame, and sex.
